A monophthong (/ ˈ m ɒ n ə f θ ɒ ŋ, ˈ m ɒ n ə p-/ MON-əf-thong, MON-əp-; from Ancient Greek μονόφθογγος (monóphthongos) 'one sound', [1] from μόνος (mónos) 'single' and φθόγγος (phthóngos) 'sound') is a pure vowel sound, one whose articulation at only beginning and end is relatively fixed, and which does not glide up or down towards a new position of ...
Monophthongization is a sound change by which a diphthong becomes a monophthong, a type of vowel shift.It is also known as ungliding, [1] [2] as diphthongs are also known as gliding vowels.
Old English had a moderately large vowel system. In stressed syllables both monophthongs and diphthongs had short and long versions, which were clearly distinguished in pronunciation. In unstressed syllables, the number of vowel contrasts was generally reduced.
Although the Old English diphthongs merged into monophthongs, Middle English began to develop a new set of diphthongs.Many of these came about through vocalization of the palatal approximant /j/ (usually from an earlier /ʝ/) or the labio-velar approximant /w/ (sometimes from an earlier voiced velar fricative [ɣ]), when they followed a vowel.
The International Phonetic Alphabet (IPA) can be used to represent sound correspondences among various accents and dialects of the English language.. These charts give a diaphoneme for each sound, followed by its realization in different dialects.
In Old English, two forms of harmonic vowel breaking occurred: breaking and retraction and back mutation.. In prehistoric Old English, breaking and retraction changed stressed short and long front vowels i, e, æ to short and long diphthongs spelled io, eo, ea when followed by h or by r, l + another consonant (short vowels only), and sometimes w (only for certain short vowels): [3]
The vowels of Australian English can be divided according to length. The long vowels, which include monophthongs and diphthongs, mostly correspond to the tense vowels used in analyses of Received Pronunciation (RP) as well as its centring diphthongs. The short vowels, consisting only of monophthongs, correspond to the RP lax vowels.
The Received Pronunciation phonemes /eɪ/ (as in face) and /əʊ/ (as in goat) are often pronounced as monophthongs (such as [eː] and [oː]), or as older diphthongs (such as /ɪə/ and /ʊə/). However, the quality of these vowels varies considerably across the region, and this is considered a greater indicator of a speaker's social class than ...
